IMPROVEMENT IN OATMEAL-MACHINES.

Specification forming part of Letters Patent No. 210,667, dated December10, 1878; application filed September 18, 1878.

To all whom it may concern:

Be it known that I, JOHN F. Evans, of Ravenna, Portage county, Ohio,have invented a new and useful Improvement in Oatmeal-Machines, of whichthe following is a specification:

My invention relates to that class of oatmeal-machines in which the catsare cut transversely into particles of the desired size.

The object of my invention is to cut the cats by depositing them on aseries of thin metallic bars having their sides in contact with eachother, and provided with short upwardprojectin g teeth or knives, whichcut the oats between them by the alternate bars having oppositelongitudinal reciprocating motions.

In the drawings, Figure 1 is a top view of the machine. Fig. 2 is a sideelevation. Fig. 3 is a longitudinal section at the dotted line inFig. 1. Fig. 4: is a cross-section at the dotted line in 2.

The thin metallic bars 0 e c and so a: are placed alternately side byside in frame a, in contact with each other, so that the grain cannotpass down between them. The knives o c are short projections on the topsof the bars, having cutting-edges, and having depressions in the top ofthe bar, between and on each side of the knives, for the meal to passout laterally through like depressions g g on each side of frame a, andalso through opening bin the frame between the two series of bars.

The bars 0 and as have reciprocating motions given to them throughpitmen f f, shafts a a,

and arms (1 d by alternately raising and lowerin g the arms by means ofpin 73.

Arms d d are connected by pin 0, which slides in slot s.

The relative motions of bars e and bars 00 are in opposite directions.

The hopper h, attached to the top of frame a, has slots s in its bottomacross bars c and 00, and wide enough to permit the oats to drop throughthem lengthwise across bars 6 and a, between knives c and c.

Fig. 1 represents a part of hopper 11., broken away to show the relativepositions of knives c c and slots 8 when arms (1 d are raised. Bylowering the arms the knives c c are moved toward each other cutting thecats between them.

The thickness of bars 6 and :1: determines the requisite fineness of themeal.

The cats which may fall endwise through slots .9 will be out between theupper edges of the knives and the sides of the slots.

1 claim as my invention- In an oatmeal-machine, the alternate parallelbars 6 and m, with their sides in continuous contact, and provided ontheir upper edges with knives c c, and depressions across the top of thebars for the escape of the meal substantially as described.

JOHN F. BYERS.
